Blue Cave – The magical blue of the Adriatic that you must experience
Located on the island of Biševo, near Komiža on the island of Vis, the Blue Cave (Modra špilja) is one of Croatia’s most fascinating natural wonders. This unique sea cave is famous for an incredible play of light that fills the interior with a magical blue glow. Every year, thousands of visitors come to witness this natural phenomenon—so if you haven’t been yet, it’s time to add the Blue Cave to your travel list!
Why is the Blue Cave so special?
The Blue Cave is known for its spectacular blue shimmer, created when sunlight enters through an underwater opening and reflects off the cave’s pale seabed. The result is an unreal shade of blue that leaves visitors speechless—making it feel as if everything inside the cave is glowing with its own light.
The cave itself is about 24 meters long, 10 meters wide, and 15 meters high, and it can only be entered by small boats. The atmosphere inside is truly unique, and the water is so clear that you can see the bottom distinctly—even though in some parts the depth exceeds ten meters.
What makes this cave special is not only its beauty, but also the story of how it was discovered. It was first described by Baron Eugen von Ransonnet in 1884, when he noticed the light phenomenon that today makes it one of the most famous sea caves in Europe. Thanks to its breathtaking scenery, the Blue Cave is a must-visit destination for nature lovers, adventurers, photographers, and anyone who wants to experience something truly unique on the Adriatic.

When is the best time to visit the Blue Cave?

During these months, the sea is usually calmer and temperatures are pleasant, making the boat ride comfortable and the island-hopping experience carefree.
Visiting in the morning is recommended, when sunlight enters at the right angle through the underwater opening and produces the most spectacular glow. Mornings are also less crowded, allowing for a more intimate experience of this natural phenomenon. In peak season, the cave can get very busy, so it’s best to book your boat tour in advance and secure your spot.
